The T-shirt hanging in Alpha Team's ready room says "Welcome to the US Army" with the acronym "BOHICA" painted underneath. This is a subtle nod to SEAL Team SIX creator Richard Marcinko who coined the term.

According to remarks and interviews made by members of the cast and crew and leaks on the internet these are some of the rumoured storyline ideas for the series if it had made it into a fifth season; - Tom Ryan would realise that despite becoming a Brigadier General his new position is essentially a meaningless administrative post, the military hierarchy has actually succeeded in sidelining him through his promotion. The Unit must adapt to his replacement, a female commanding officer who is a political appointee with little or no experience of covert operations.
- Devestated by Molly leaving him Jonas Blane has an affair with Bridget Sullivan. However she breaks it off when she realises that his feelings for her are clouding his tactical judgement. He begs Molly to take him back but she repeats that he must choose between her and the army.
-Tiffy becomes pregnant with her and Mack's third child and he applies to become an officer in order to better provide for his family. However their eldest daughter Lissy runs away from home and when Mack recovers her they discover she is pregnant. The couple must then decide whether or not to allow her to have an abortion. After a car accident Tiffy miscarries whilst Mack is overseas and they decide to allow Lissy to have her child and raise it as their own.
- Bob Brown is badly injured in a training accident and faces the very real possibility that he may never again be a frontline soldier. Kim's career at the radio station takes off and she becomes the main earner for the family creating tension between them.
-Charles Grey's new bride has difficulty adjusting to the secrecy surrounding The Unit and her new role as an army wife.
- Bridget Sullivan discovers that Sam McBride is gay and he agonises over whether or not to come out to his macho colleagues. -The team discover that the CIA has illicitly created it's own special commando force with several ex-Unit members included within it's ranks. When General Ryan tries to get this new organisation shut down his ex-wife reveals to him that a mole deep within The Unit has been leaking classified information to the highest bidder. The Agency has recruited it's own group of elite covert warriors because it can no longer trust The Unit to carry out secret missions on it's behalf. The team's hunt for the traitor within their own personnel would have been the major story arc for the season.
-Subplots would have included the recruitment of more female soldiers into The Unit and a group of journalists/human rights activists attempting to expose the organisation and have them prosecuted under international law for their actions. The Unit would also have crossed swords with the character of 'Super Seal', an egotistical former navy special forces officer who now hires himself out as a celebrity mercenary/bodyguard, motivational speaker and media expert on covert operations.

Q

What happened to the facial scar that Mack Gerhardt (Max Martini) had in season one? It just disappeared in later episodes.

A

In the early episodes of season one Mack Gerhardt (Max Martini) has a large facial scar on his left cheek. In most episodes he has a beard and it might not be as noticeable. In later episodes such as "Change of Station" he shaves and there is no longer a scar? It is suggested he had cosmetic surgery as the scar would have made him too distinctive for the undercover role.

Q

How would the series have ended if renewed for a fifth season?

A

According to remarks and interviews made by members of the cast and crew and leaks on the internet these are some of the rumoured storyline ideas for the series finale;
The series would end with Jonas beginning to suffer with combat stress. This is aggravated by Bridget Sullivan being mortally wounded on a mission, her dying words forgiving Sam McBride for his fake attempted rape of her. As a result Jonas retires from the army and joins Molly in her real estate business. Mack would become an officer and he and his family would move to a permanent posting elsewhere arranged by General Ryan, giving him a conventional army training job without any combat role. Bob would leave the army due to his injuries and go to law school but he would maintin his links with the CIA and work as a training instructor/legal consultant for them and act as their liaison with The Unit. He is intended by the CIA to be their inside man on The Unit through his contacts but it is later revealed that he is actually still working for Tom Ryan and is effectively The Unit's mole within the agency. Charles Grey would be promoted to the new team leader with Sam McBride as his deputy. General Tom Ryan would get back together with his ex-wife and call in the numerous favours owed to them and his men to have The Unit once again placed under his command. The series would end with the entire cast assembled to watch Bob, Charles and Sam put potential new recruits to The Unit through their paces in order to bring their team up to full strength.
According to an interview executive producer Shawn Ryan gave to The Futon Critic "[David] Mamet and I and our writers, we came up with a lot of great stuff," Ryan said about his pitch to CBS executives for a potential fifth season. "It was going to be a whole new show in the sense that we were going to be training some young people, Bob was going to be training some people for a whole new organization. Jonas was finally going to be seeing his run end......The final season was going to be, I figured the fifth season was going to be the last... It was going to be a long, sort of final mission for Jonas. He's not medically cleared, Mac has to go in and sort of change the medical records so that Jonas can keep on [going on missions]. We had a whole thing planned, it was going to be good."
